GIS Data and Websites

Where can you get data to use in a GIS? The UM Libraries have geospatial data in the collections, many websites have free data, and data can also be purchased.

Maryland

The Maryland State Data Center has already compiled and analyzed a great deal of census data for the state and localities.  Take some time and investigate this website--it is a gold mine!

Note: Many of the CDs with GIS data in the library's collection must be used in house at McKeldin Library.
